ABSTRACT:
A method for the derivation of indicia of vertebral morphology from data obtained by lateral digital scans of the vertebrae obtains a matrix of data values assembled from a lateral vertebral scan. The matrix is analyzed to locate local minima and maxima from which the borders of the vertebral body may be calculated. Once the borders of the vertebral bodies are derived, one or more of several useful indicia of vertebral condition can be calculated. These indicia are associated with clinically recognized modes of vertebral condition. The data values in the matrix are also scanned for areas of unusual densities so that nonhomogeneous regions are not used in measuring overall bone mineral density of a vertebra.
